Checking your internet information, ie IP address, Router Address (Default Gateway) and Subnet Mask, can be a very important step in diagnosing an internet network.
To check all of this information in Windows, open the command prompt (Start -> Run -> cmd) and type “/ipconfig /all”. This will present you with a screen of information that tells you all of the information you need to know about your internet connection.
In Mac OS X, open your Network Preferences (Applications -> System Preferences -> Network). Then click “Advanced” -> then the “TCP/IP” tab on top. This screen will show you all of the information you need.
Checking these numbers is the first step in the door to learning how to fix a large number of network related problems, so being able to tell your IT professional these numbers will greatly help them out.
Keep a straight head,
A good friend of mine sent me a message saying that his internal iSight wasn’t working anymore on his MacBook.
For this issue the first thing to do would be to go to the Disk Utility, Applications -> Utilities -> Disk Utility. Then click on Macintosh HD, then click “Repair Permissions”
This should clear up any issues that your hard drive is having with the iSight.
Yet for some people this doesn’t work. The next step is to shut down your laptop, and remove the battery. Hold down the power button for 5-10 seconds with the battery still out, then put the battery back in and turn on the machine.
This should clear out the system BIOS for any issues with the iSight as well. From there, if your iSight continues to malfunction it is most likely hardware based, and unless you want to void your warranty you need to at least take to it apple care.

So, since the first step in diagnosing and repair any type of technology is being aware of exactly WHAT you have. This guide is focused towards computers for the most part, seeing as few electronics need to be profiled in the same way that a computer does.
For Windows users:
The best way to find a good system profile is using the DxDiag command from your ‘Run’ menu. To run DxDiag, click “Start” -> “Run” -> type “dxdiag” (without the quotes) and hit enter.
An example of a DxDiag window
DxDiag is a executable file that will bring up a window with all types of information about your computer. Unless you are very interested in understanding the types of hardware that you have under your hood then simply click the Save button at the bottom of the window and save the file as a .txt.
This file will give me the relevant information about your system so that I can properly diagnose and instruct you.
For Mac users:
In Mac OS X the system profiler is the best way to go. To open the system profiler, open Finder -> Applications -> Utilities -> System Profiler
Then go to File -> Save As, then select “Rich-Text Format (.rtf)”
Again, this will give me the relevant information about your system so that I can properly diagnose and instruct you.
